This is my second functioning robot. All the parts are recycled, so it didn't cost me more than a bit of time. The schematics can be found all over the internet, for it's just another BEAMbot (the one using 2n3904 and 2n3906). The only change I made is instead of FLEDs I've used some serial-placed diodes. This way I can choose at what voltage the circuit will "fire".
